/* Shared tablet UI framework — leasing-office tablets.
 *
 * Design principles:
 *   - 56px minimum tap target (≥48px is iOS HIG, ≥48dp Android — go higher for gloved hands)
 *   - 22px+ body text, 28px+ form labels (readable across the office)
 *   - High contrast (always passes WCAG AA, often AAA)
 *   - Single column layout always — no horizontal scroll
 *   - Sticky bottom action bar — primary CTA always within thumb reach
 *   - Inline real-time validation (no submit-to-find-out-it's-broken)
 *   - Idle reset (90s default) returns to start screen
